Chapter 7, Problem 12E
A matrix M with i rows, j columns can be transposed into a matrix N having j rows and i columns by simply setting the value of Na,b equal to the value of Mb,a for all relevant values of a and b.
- a. Write a function t that takes as an argument a 4 × 5 matrix and a 5 × 4 matrix. Have the function transpose the 4 × 5 matrix and store the results in the 5 × 4 matrix. Also write a m routine to test the function.
- b. Using variable-length arrays, rewrite the t function developed in exercise 12a to take the number of rows and columns as arguments, and to transpose the matrix of the specified dimensions.

Write a function that takes one input, a matrix X. Your function should modify X and return the modified version of X as an output. Assuming that X
has m rows and n columns:
When m is equal to n, modified X should be the same as X.
When m is greater than n, the modified version of X should be m x m. New columns should be added to the right of the original columns of X, with
each new element having a value that is one less than the element in the column to the left. For example, the matrix:
2 3
4 6
Would become:
2321
4 65 4
8987
1210
When n is greater than m, the modified version of X should be n x n. New rows should be added to the bottom of the original rows of X, with each new
element having a value that is one more than the element in the row above it. For example, the matrix:
2345
468 10
Would become

- R Programming - Rmarkdown: 1. Given two vectors x and y of equal length, in one line of code (in the function body), write a function find_max_logical() that will output a single logical vector that is TRUE at the indices where the maximum values in x and y are. For example, given the below vectors: x <- c(Inf, 3, 2, 6, 99) y <- c(12, 1, 0, 40, 5) # You should return (without manually creating the vector with c()) c(TRUE, FALSE, FALSE, TRUE, FALSE) # Noting that Inf and 40 are the max values of x and y respectively, ## at the 1st index of x and the 4th index of y. Please test your functions on the following test inputs in your submission: # test case 1: x = c(Inf, 3, 2, 6, 99), y = c(12, 1, 0, 40, 5) # test case 2: x = 1:5, y = 1:5 # test case 3: x = c(1, 4, 9), y = c(1, 4, 2)arrow_forward1. Write a function (call it mylm) that takes two inputs: a vector y of n elements and a matrix X of n times k elements, where n should be greater than k, and returns three outputs: bhat = solve(X'X)X'y, X'X and X'y (the prime symbol means transpose). Use the attr method to return the second and third outputs.

- This is not a graded question so please don't disregard it as if it is. Thank you in advance professor!arrow_forwardIn Python Pleasearrow_forwardWrite a function that takes a vector of integers as an argument and returns a new vector with the same elements as the input vector, but with all odd elements replaced by their square root and all even elements replaced by their square. The function should use a loop and the modulo operator to determine whether an element is odd or even. To solve this problem, you will need to use a loop to iterate over the elements of the input vector, use the modulo operator to determine whether each element is odd or even, and use an if-else statement to determine what action to take for each element. This question requires knowledge of loops, the modulo operator, and if-else statements in R. It is a relatively advanced question and may be challenging for those who are not familiar with these concepts.arrow_forward
